The aim of our study was to investigate the possible effect of acenocoumarol, which is indicated for nonneurological disease, on headache.Background.–

It has been suggested that anticoagulation can have beneficial effects in the control of migraine attacks.Methods.–

Four hundred randomized patients on oral anticoagulant therapy were asked to complete a questionnaire regarding their headaches.Results.–

Headache was present before or during oral anticoagulation in 166 (66 migraineurs and 100 nonmigraineurs) of 326 respondents. The major finding was that oral anticoagulation produced improvement in 63% of patients with migraine versus 38% of patients with nonmigranous headache. Improvement was related to the severity of migraine but not to age.Conclusions.–

Oral anticoagulant therapy can improve migraine. The way in which anticoagulant therapy acts on migraine is unknown, but potential mechanisms include its effect on platelet aggregability and pharmacological effects such as suppression of enhanced nitric oxide.
